DANIEL C. JENKINS, OF CLARKSBURG, WEST VIRGINIA.

Encina-REGULATOR.

Specicaton of Ltters Patent.

Application led March 6, 1916. Serial No. 82,478.

To all whom t may concern:

Be it known that, I, DANIEL C. JENKINS, a citizen of the United States,residing at Clarksburg-in the county of Harrison and u State of lV estVirginia, have invented certain new and useful Improvements in Engine-Regulators; and I do hereby declare the following to be a full,clear, and exact description" of the invention, such as will enableothers skilled in the art to which it appeitains to make and use thesame.

This invention relates to engine regulators, and has for anobject toprovide a construe.- tion especially adapted for use in conjunction withinternal combustion engines 4to prevent the introduction of the fullcharge of gas at starting and thereby eliminate the intense wasteful anddamaging explosions at starting, and also facilitating starting by4reason of the compression in the cylinder being less than the normalrunning compression. A further object of the invention is to provide agovernor in conjunction with an internal combustion engine forcontrolling the action of the valves as an ordinary speed regulator,with improved means interposed between the governor and the valves fortemporarily partially closing the valves at starting, with means forgradually returning the parts to normal after the engine has started.

lVith these and otherobjects in' view .the invention consists in certainnovel features of construction, combination and arrangement of parts aswill be hereinafter more fully described and claimed.

` In the drawings Figure 1 is a diagrammatic view showing theconnectionof the improved device with an internal Ycombustion engine.

Fig. 2 is an enlarged detail sectional view of the regulator.

Like characters of reference designate corresponding parts throughoutthe several views.

The. improved device which forms' the subject-matter of this applicationisadapted to be connected and operated in conjunction with any usual andordinary type of eXplo-v sive engines, here shown conventionally only asvalve housing 10 with a valve 11 mount-- ed therein. The valve 11 isactuated by a bell-crank lever 12 which in turn` is actuated from abell'crank lever 13 through connec/ting devices including a linkcomposed of the two parts or sections 14 and 15. The

lin any usual and ordinarv .the length thereof,

bell-crank lever is controlled by. a governor 16 of any usual andordinary. type, driven manner as by the Interposed in the run of thelilik 14-15 is mechanism for varying its length. This is here shown as acylinder 18 rigidly connected with one of the sections, as the section 14, with a piston 19 slidably mounted within the cylinder 18 and rigidlyconnected with the other section, as 15, o f the link.-

Within the cylinder 18 is a spring 20 normally tending to hold thepiston at the eX;

treme of its movement and the link 14-15 at lits greatest length. Meansis provided, however, as the flexible pipe 21 for actuating saidmechanism pneumatically by admitting air to the cylinder 1.8 against thepiston 19 to move the piston within the cylindenagainst the tension ofthe spring 20. The air from the flexible pipe 21 passes through thevalvehousing 22 check valve 23. It is well known, of course, thatcompressed air is used in starting large internal combustion engines,and at the vtime the compressed air is employed for this purpose it isby my invention also admitted through the pipe 21. As soon as the enginestarts the compressed air is shut oif, and the air is trapped by thevalve 23 in the cylinder 18, holding the piston with the combined link14515 shortened and the adjustable stop 24 against the gland 25. llVhen,however, the air is shut off the trapped air leaks through the bleederQGunder the pres- Sure of the spring 20, permitting the piston lifting the'Y 19 to 'return slowly to normal and the composition.

Throughout the specification referencelias been made to admitting air tothe cylinder 18. It is to be understood that the air is used only asillustrative of any Huid under pressure conveniently at hand for`actuating the piston within the cylinder.

I claim i 1. The combination with an engine valve, a centrifugalgovernor, devices connecting .said valve and governor; of mechanisminterposed insaid devices to temporarily vary and means receiving fluidpressure simultaneously with a starter and connected tosaid mechanism.

'2. 'Ihe combination with av valve, a governor, and a connection betweenthem; of

ofmechanism to vary the length ofsaiddevices, pneumatic means foractuating said mechanism, and'means to automatically restore the devicesto normal.

4. The combination with an engine valve anda governor therefor; of alink composed Vof alined sections connected respectively to the; valveand governor, members connected with, the sections and telescopic oneach other, and means receiving air pressure simultaneously With astarter, operative to slide said members by said pressure to reducethe'length ofthe link, and means to gradually restore the parts tonormal after starting has been accomplished.

5. The combination with an engine valve and a' governor therefor; ofalink connecting the valve and the governor composed of sectionsslidable relative to each other, means, receiving air pressure asutilized for startingthe engine, to vary the length of the link, andmeans to gradually restore the parts to normal after starting has beenaccomplished.

' 6;l The combination of a valve and a governor therefor, a linkconnecting the valve and governor 'composed of sections, a cylindercarried by one section, a piston carried by th other section slidableWithin the cylinder, a spring tending to hold the piston at one end ofthe cylinder, means to admit air to the .cylinder to move the pistonagainst the tension of the spring, means to trap the air Within thecylinder, and means to permit the air to gradually bleed out of thecylinder under the expansion of the spring.

7.-'Ihe combination With a valve and a governor therefor, a linkconnecting the valve and governor and composedof sections, a cylindercarried. by one section, a pistonarried by theY other and slidablewithin the cylinder, a spring tending to hold v thevpiston at one end ofthe cylinder, a flexible pipe to admit air to said end of the cylinderto move the ypiston against the tension of the spring, a check valve insaid pipe to trap the air Within the cylinder, and a bleed opening topermit the air to gradually escape from the cylinder under the eX-pansicn of the spring. Y

8. The combination with an engine valve,

.a governor therefor; of a link connecting' the valve and the governorcomposed of sections, members connected With the sections and slidablerelative to each other, and means, .receiving fluid pressure passing toCopie'of this patent may be obtained for ve a the engine for startingpurposes, voperative to slide the members at starting to. vary thelength of the link. A

.9. Thel 'combination of a valve and a governor therefor, a linkconnecting the valve and governor and composed of sections, a cylindercarried Vby one section, a piston carried by the other section andslidable Within the cylinder, means to admit air to the cylinder to movethe piston in one direction, means to trap. the air vwithin thecylinder, and means to permit the air to gradually bleed out of thevcylinder and the piston to move in the other direction.
